Nonreflective, Silicon SP4T Switch, 0.1 GHz to 6.0 GHz

The HMC7992 is a general-purpose, nonreflective, 0.1 GHz to 6.0 GHz, silicon, single-pole, four-throw (SP4T) switch in a leadless, surface-mount package. The switch is ideal for cellular infrastructure applications, offers high isolation of 45 dB typical at 2 GHz, and a low insertion loss of 0.6 dB at 2 GHz. It offers excellent power handling capability up to 6.0 GHz, with input power of 1 dB compression point (P1dB) of 35 dBm at 5 V operation. The HMC7992 has good low frequency input power handling below 0.1 GHz and can operate well down to 10 kHz, with a typical 1 dB compression of 21 dBm and an IIP3 of 37 dBm at 1 MHz.

The on-chip circuitry allows the HMC7992 to operate at a single, positive supply voltage range from 3.3 V to 5 V, and as well as a single, positive control voltage from 0 V to 1.8 V/3.3 V/5.0 V. A 2:4 decoder integrated in the switch requires only two controlled input signals, with a positive control voltage range from 0 V to 1.8 V/3.3 V/5.0 V, to select one of the four radio frequency (RF) paths.
